The present invention relates to the supplying power to burners for oxy-fuel combustion glass melting furnaces, including a fuel injecting means and a hot oxygen power supplying means, the dispensing of oxygen being carried out so as to develop a staged combustion, a fraction of the oxygen being concurrently injected into the fuel, said oxygen being supplied essentially without heating prior to the supplying thereof into the fuel injecting means.

Power supply for hot oxygen burner

Variable momentum burner assembly for separately injecting fuel gas and oxidant in a combustion zone, comprising at least two fuel gas canals, at least one oxidant canal and a fuel gas distributor, whereby the at least two fuel gas canals comprise an inner fuel-conducting passage forming an inner fuel gas outlet and an outer fuel-conducting passage forming an outer fuel gas outlet, said inner and said outer fuel-conducting passages being coaxially arranged; and whereby said fuel gas distributor comprises a first fuel gas chamber in fluid connexion with the inner fuel-conducting passage of the at least two fuel gas canals and a second fuel gas chamber in fluid connexion with the outer fuel-conducting passage of the at least two fuel gas canals.

Burner assembly and method of combustion

The invention relates to a method for the combustion of a fuel using an oxygenated gas, in which a jet of fuel and at least two jets of oxygen-rich oxygenated gas are injected. According to the invention, the first jet of oxygen-rich oxygenated gas, known as the primary jet, is injected such as to be in contact with the jet of fuel and to produce a first incomplete combustion, the gases produced by said first combustion comprising at least one part of the fuel, and the second jet of oxygen-rich oxygenated gas is injected at a distance I1 from the jet of fuel such as to combust with a first part of the fuel present in the gases produced by the first combustion. Moreover, a low-oxygen oxygenated gas is injected at a distance I2 from the jet of fuel such as to combust with a second part of the fuel present in the gases produced by the first combustion, I2 being greater than I1. The invention also relates to the burner used to carry out the method and to the use of said method for the heating of a glass filler or for a reheating furnace.
